After reading some of the forgoing I thought I'd give my MW a run as I've not even tried it since receiving it last Thursday. My initial check on my 00 industrial line was interesting in as much as it wasn't too bad forwards, but backwards whoaaa, terrible noise like a pickup catching spokes on a wheel. A quick visual check revealed nothing amiss so it was on to the rollers!
Around about half an hour each way and a retest on the track revealed the noise had gone but it's running still left something to be desired, so on to a comparison test against my Rapido fireless (which has not been run in to any degree at all) and I'm afraid it knocked spots off the MW certainly for quiet slow speed running. More running in is needed methinks.
